![(FILES) In this file photo taken on March 19, 2018 Two technicians inspect bitcon mining at Bitfarms in Saint Hyacinthe, Quebec. Investors in a cryptocurrency exchange who lost access to tens of millions of dollars when the website's Canadian founder died abruptly, are demanding his body be exhumed to rule out any chance that he faked his own death. The case focuses on the sudden death of QuadrigaCX founder Gerald Cotten, who passed away aged 30 from Crohn's disease, an inflammatory bowel condition, in December 2018 while traveling in India, taking all the passwords to the site's funds with him to the grave.
